Fact 5. Iodine Deficiency and Weight Gain: Understanding the Link
An unexpected side effect of iodine deficiency can be weight gain. As iodine is integral for the production of thyroid hormones, its deficiency can lead to hypothyroidism – a condition characterized by low levels of these hormones. As these hormones regulate the body’s metabolism, their deficiency can lead to metabolic slowdown, which can, in turn, lead to weight gain.
When the body’s metabolic rate slows down, it burns fewer calories at rest. This means even if an individual’s food intake remains unchanged, they may start to gain weight due to the decreased calorie burning. Furthermore, the slowed metabolism can also lead to decreased sweating and thus a decreased release of water weight, contributing further to weight gain.
It’s also important to note that the weight gain associated with iodine deficiency and hypothyroidism is often accompanied by a particular form of swelling, known as myxedema. This type of swelling, characterized by its puffiness and resistance to indentation, can make the weight gain appear more significant.
However, it’s important to note that not everyone with iodine deficiency will experience weight gain. The effects of iodine deficiency are complex and can vary significantly between individuals, influenced by a multitude of factors like diet, lifestyle, and genetics.
All in all, the potential link between iodine deficiency and weight gain underlines the multifaceted nature of this micronutrient shortfall. It serves as a reminder of how interconnected our bodily systems are and how a deficiency in one area can have far-reaching impacts on various aspects of our health and wellbeing. (5)
